High speed serial digital data to analog signal converter |
摘要 |
An Ethernet-type local area network having multiport repeaters and nodes within a specified distance of the hub is able to communicate high speed digital data over multiple pairs of twisted-pair wires using long symbol group-type ternary coding. Bundle mode termination minimize impedance mismatches. Low-frequency collision detection circuitry permits detection of packet collisions on an a.c.-coupled network. Precise serialized digital to analog conversion is realized using chains of gates to form delay elements with precise delays.
